What was the purpose of Watson and cricks experiment?

Watson and Crick's experiment aimed to elucidate the structure of DNA, the molecule that carries genetic information. By utilizing models and existing data from X-ray diffraction images, particularly those produced by Rosalind Franklin, they proposed the double helix structure of DNA. Their work provided a foundational understanding of how genetic information is stored and replicated, revolutionizing the fields of genetics and molecular Biology.
